The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise. 
Answer:
Kindly check explanation 
Step-by-step explanation:
If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.
Hypotenus² = opposite² + adjacent²
(refer to attached picture)
x² = 6² + 8²
x² = 36 +. 64
x² = 100
x = sqrt(100)
x = 10 meters
You can use the actual depth value to obtain the actual solution to your question.

C. point K is (3,-3) and the dilation moves from 3 to 1 so you divide both X and Y coordinates by 3 to get (1,-1)
hope this helps.
        
                    
             
        
        
        
Answer:
c
Step-by-step explanation:
3⁶ * 4² * 12 = 3⁶ * 4² * 4*3 = 3⁷ * 4³
3³ * 4 * 5
GCF= 3³ * 4
Only common factor with minimum power
 
        
             
        
        
        
Answer:
